nterchange-newline”> Objective
Cover all the subjects from the standard books.
Time bound practice :- In exam we get 180mins for 120 objectives, 1.5mins for each . So sit for 30mins at a stretch and solve
45obj. This will help you develop speed and accuracy, both of them are very important for ESE exam.

Follow Cross Referencing Method : even covering the standard books , doesnot ensure comprehensive coverage of syllabus.
There are bound to be topics which we skip/ don’t give much importance .

Here the method of cross referencing helps. Whatever objectives you are not able to solve , please study the corresponding topic
from the book. This will include topics which are entirely NEW or topics which you might have skipped. This will increase your
depth of preparation
○ Mark the objectives which you are not able to solve . Revise only these before Coaching test OR final ESE exam.
After covering one subject, solve all the previous year questions ( past 15yrs 2000-2014 will suffice ).
While solving the objectives , please keep the following trivial things in mind.
If you have time , please solve questions, given @ the back of each chapter. ( solved ones ) . This will broaden your horizon and give
you more practice.

Time bound practice :- In exam we get 180mins for 200 marks subjective, 9 mins for every 10marks . While practicing previous year
questions, make sure you complete 10marks questions within 9 mins.

You may not be able to do this in the initial stages of preparations . But I think by April – May , it will be easy.
This will help you develop speed and accuracy, both of them are very important for ESE exam.
• Previous Year questions are Sin-qua-non . Please practice them and mark the important ones. This will help in revision.
Subjective
• For people facing time crunch , please give Made easy GS class notes a few readings
• Solve previous year GS questions of ESE , CDS , CSE exam. Many questions are directly repeated.
• Practice English from Made easy book – this is all that is needed for English .No other book is needed.
• Attempt whole – heartedly.

This is the transcript of my ESE 2014 interview , I typed it down when I came back home. Hope this helps you
– Final marks awarded – 120/200.
– Total Duration 25mins
– Board Chairman – Mr. Manbeer singh
.
Chairman : So Abhay you are from lucknow ?
Me : yes , sir.
CM : Abhay, you did your grad in 2012 , a long time since then , what have you been doing ?
Me: sir, I have been preparing for Engg services exam – last year , I qualified in the written , but missed final selection by just 5 marks , this year I have given the exam
with improved performance.
CM : good ….. there are many civil engineering structures in the world, many bridges , buildings , dams , what do you admire the most ?
Me : sir , Burj Khalifa , the tallest building in the world , Three gorges Dam – biggest dam – ( CM interrupts )
CM : ok we will stick to the building you mentioned ___ Burj Khalifa – …what do you find special in it , apart from the fact that it is that tallest building in the world ?
ME : sir ,in high rise buildings , wind load assumes importance , it can cause toppling of structure , it causes vortex shedding in which the building starts to oscillates
either side and makes the inhabitants very uncomfortable – the design of Burj Khalifa – successfully dealt with these problems. – and this set an example for all high rise
construction. Moreover Concrete used was of very high strength – 80MPA – and it required high workability and good Mix proportioning to pump it to such a height.
CM: you mentioned something about the strength …80…… so how was the strength increased ?
ME : it was done in many ways – increasing the fineness of cement , increasing C3S content , air entrainment.
CM: ok, what is curing ?
ME: Sir , curing is a process in which favourable conditions are created for hydration process to continue unabated. There are many types of curing – water curing ponding , membrane curing – where water is scarce, temperature high – done to prevent evaporation of water from surface , steam curing at low pressure and high
pressure
CM : ok – so Is ice used for curing ?
ME : no , sir .. It will interfere with the hydration process – temperature determines the rate of hydration . It is an important aspect in cold weather concreting
CM : I was seeing that ….. In that dam ….. ice was used …….. ?
ME : yes sir , in dam, mass concreting is done , so due to risk of cracks— concrete in placed in blocks , now we wait for shrinkage to happen so as to plug the gaps
formed – but shrinkage in natural process will take 100 years complete – we have only 5-6 years – so got cold water is poured over the dam like in Three gorges Dam –
and sir ice can also be used.
CM : ok …. Passes onto M1
M1 : what is the use of nanotechnology in civil engineering ?
Me : sir , we can use it in the design of inverted filters for seepage control in dam – here we have to prevent the soil particles from coming up – meanwhile allow water
to flow out thus allowing pore pressure to dissipate.
M1 : ok … tell me in respect of concrete technology ?
Me : we can use it in improving the strength of transition zone in cement paste – all the adverse qualities associated with concrete like cracks is related to it , moreover
using it, we can increase the ductility of concrete – thereby eliminating the use of steel altogether.
M1: How does fineness influence hydration ?
Me : more fine cement has more surface area for the hydration process- hence hydration is speeded up – strength is developed early.
M1 : ok .. how can we use nanotechnology in paint ?
Me: sir , requirements of a paint are – it should be impermeable to flow of water – should be chemically inert – durable – using nanotechnology -atoms , molecules , ions
could be studied and properties suitably altered – to obtain favourable paint.
M1 turns towards CM nods and says Ok — CM passes onto M2:
M2 : ok we were talking about concrete pumps… tell me what pumps were used ?
Me : sir , concrete pumps of reciprocating type were used
M2 : what is the principle in it ?
Me: sir , It works on positive displacement – a plunger moves to and fro and imparts force to the fluid – so displacement takes place
M2 : pipes are used in water supply also – what is the difference between the two?
Me: sir , in water supply there is no solid particles but in concrete pumping solid particles are present so pump should be designed such no wear and tear of the pump
takes place .
M2: what material is the pump made of ?
Me: Cast iron , bcoz it can better withstand the tensile , compressive , bearing stress withstand during the process
M2: Concrete has solid particles that can stick in between the plunger – so how will you tackle that ?
Me : Sir , proper mix proportioning is done to ensure that segregation doesnot take place.
M2: okkk so ……… pumps are also used for ground water extraction also – what kind of pumps are used ?
ME : sir , hand pumps are used – reciprocating nature
M2 : what other methods ?
Me : sir , tube well and bore wells are made
M2: what kind of pumps are used in tube wells and bore wells ?
Me : sir , we have reciprocating and centrifugal pumps, either one of them is used … I don’t know the exact one
M2 : what is the difference between the two ?
Me: sir , basic principle on which they work – in centrifugal kinetic energy converted to pressure energy and in reciprocating – force – displacement – priming
M2 : how will the water come out of the borehole ? On its own ?
Me: no sir , after borehole is dug to the required depth of water bearing stratum – – suction is applied to take out the water.
M2 : ok but suppose there is a farmer – how will he know – he doesnot understand priming and all ?
Me: sir , reciprocating pump has continuous type of flow while centrifugal has variable – electricity use in centrifugal pump and not in reciprocating
M2 : ok…… so tell me what are the types of canals ?
Me : sir , major canals – branch canals – distributary canals – watercourses
M2 : ok so tell me – how to measure the discharge of canals ?

M2 : ok so tell me – how to measure the discharge of canals ?
Me : sir ,discharged is measured through weirs – metering flumes – venturimeter .
M2 : How will you measure the discharge using venturimeter ?
ME : 3 second pause : sir , venturimeter is placed along the flow and piezometer is put to measure the pressure difference and then using Bernoulli theorem discharge is
measurement .
M2 turns to CM – nods and CM passes over to M3
M3 : ok , so what kind of sand is used in the construction ?
Me: sir , coarse sand is used – for example in Burj Khalifa – desert sand was available – it was too fine – load bearing capacity is less – so not used
M3 : there is zoning of sand.
ME : yes sir , zone 1- zone 4
M3 : what is zoning of sand ?
ME: method of gradation of sand
M3: suppose zone 2 sand is not avb zone 3 is avb – what will we do ?
Me : sir , ground improvements techniques will be used – like Vibrofloatation – dynamic compaction – compaction grouting
M3 : yes ok … but we have already talked about that – so tell me in respect of sand as building material – if zone 2 is present instead of zone 3 ?
Me : sir , mix design procedure will be used – there are tables in IS 456 – we will use them in design
M3 : accepts the answer — ok so what will be changes in mix design in above situation ?
Me: sir , sand amount will increase
M3 : are you sure …sand amount will increase or cement ?
Me : yes , it will increase. ( wrong here – I didn’t know the correct answer )
M3 : in black cotton soil – which type of piles are used ?
ME : sir , undreamed piles are used
M3 : ok ,what are the kinds of piles ?
Me : sir , piles are classified acc to type of material used – method of installation like – driven pile – bored pile and —– ( interrupts )
M3 : tell me the diff between driven and bored piles ?
Me : sir , in bored piles – borehole is made – then reinforcement cage is lowered in then concreting is done – while in driven pile – casing is driven in by blows of a
hammer then reinforcement cage is lowered in then concreting is done
M3 : good – what measures do we take to prevent the caving in of excavations ?
ME : sir , bentonite slurry is used – it forms a hard covering ard the soil strata and prevents caving in.
M3 looks at CM – ok sir … CM to me : ok , your interview is over , you may go.
